The traditional model of "homo economicus"
- that ever-rational individual, always maximizing his self-interest
in competition with others is now acknowledged as unrealistic.
It is a fear and scarcity model based on the early reptilian
brain and the territoriality of our primitive past .This bleak
model of human behavior at the heart of economics is not only
dismal - but increasingly proven wrong by many other scientists
and much recent research by neuroscientists, microbiologists,
psychologists, anthropologists and yes, game theorists. This
is why many recent Bank of Sweden Economics prizes have gone
to scientists studying human behavior beyond the economics
profession, from psychologists to game theorists John Harsonyi,
John Nash and Reinhard Selten in 1994.

Charles Darwin's original notebooks, shows
that Darwin was more interested in the human capacity to bond
and trust as factors in Human Success. A chorus of scientists
are now calling for the Nobel Prize in Economics to be abolished.
